Exegetical and Hermeneutical Commentary of Genesis 36:32
And Bela the son of Beor reigned in Edom: and the name of his city [was] Dinhabah.
32. Bela the son of Beor ] In the Hebrew the addition of the letter m would give us the proper name “Balaam the son of Beor” (Num 22:5). So Targum of Jonathan reads. Hence some have conjectured that we have here an alternative tradition respecting Balaam, as king of Edom.
Bela is also the name of a town, Zoar (Gen 14:2).

Where he was born or dwelt, and so in the rest. The diversity of their cities makes it probable, that these kings had not their power by succession, but either by election, or by usurpation, according to Isaacs prophecy of them, Gen 27:40; By thy sword thou shalt live.

And Bela the son of Beor reigned in Edom,…. His name was not Balac, as the Septuagint version, which may lead to think of Balak king of Moab; nor is this the same with Balaam, the son of Beor, who lived ages after, as some in Aben Ezra: who he was we know no more of than what is here said; he was the first Horite king, and is placed by Mr. Bedford i in A. M. 2002:
and the name of his city [was] Dinhabah, the place either where he was born, or where he had been governor before, but of it we read nowhere else.
